NAME
     cal, ncal -- displays a calendar and the date of Easter

SYNOPSIS
     cal [-3hjy] [-A number] [-B number] [[month] year]
     cal [-3hj] [-A number] [-B number] -m month [year]
     ncal [-3hjJpwy] [-A number] [-B number] [-s country_code] [[month] year]
     ncal [-3hJeo] [-A number] [-B number] [year]
     ncal [-CN] [-H yyyy-mm-dd] [-d yyyy-mm]

DESCRIPTION
     The  cal  utility displays a simple calendar in traditional format and ncal
     offers an alternative layout, more options and the date of Easter.  The new
     format is a little cramped but it makes a year fit on a 25x80 terminal.  If
     arguments are not specified, the current month is displayed.

     The options are as follows:

     -h      Turns off highlighting of today.

     -J      Display Julian Calendar, if combined with the  -e	option,  display
	     date of Easter according to the Julian Calendar.

     -e      Display date of Easter (for western churches).

     -j      Display Julian days (days one-based, numbered from January 1).

     -m month
	     Display  the  specified  month.  If month is specified as a decimal
	     number, it may be followed by the letter `f' or `p' to indicate the
	     following or preceding month of that number, respectively.

     -o      Display  date  of	Orthodox  Easter  (Greek  and  Russian	Orthodox
	     Churches).

     -p      Print the country codes and switching days from Julian to Gregorian
	     Calendar  as  they are assumed by ncal.  The country code as deter-
	     mined from the local environment is marked with an asterisk.

     -s country_code
	     Assume the switch from Julian to Gregorian Calendar at the date as-
	     sociated with the country_code.  If not specified,  ncal  tries  to
	     guess  the  switch date from the local environment or falls back to
	     September 2, 1752.  This was when Great Britain  and  her	colonies
	     switched to the Gregorian Calendar.

     -w      Print the number of the week below each week column.

     -y      Display a calendar for the specified year.

     -3      Display the previous, current and next month surrounding today.

     -A number
	     Display the number of months after the current month.

     -B number
	     Display the number of months before the current month.

     -C      Switch to cal mode.

     -N      Switch to ncal mode.

     -d yyyy-mm
	     Use yyyy-mm as the current date (for debugging of date selection).

     -H yyyy-mm-dd
	     Use yyyy-mm-dd as the current date (for debugging of highlighting).

     A	single	parameter  specifies the year (1-9999) to be displayed; note the
     year must be fully specified: "cal 89" will  not  display	a  calendar  for
     1989.  Two parameters denote the month and year; the month is either a num-
     ber  between  1  and  12, or a full or abbreviated name as specified by the
     current locale.  Month and year default to  those	of  the  current  system
     clock and time zone (so "cal -m 8" will display a calendar for the month of
     August in the current year).

     Not  all  options	can be used together. For example "-3 -A 2 -B 3 -y -m 7"
     would mean: show me the three months around the seventh month, three before
     that, two after that and the whole year.  ncal will warn about these combi-
     nations.

     A year starts on January 1.

HISTORY
     A cal command appeared in Version 5 AT&T UNIX.  The ncal  command	appeared
     in FreeBSD 2.2.6.

AUTHORS
     The   ncal   command   and   manual   were   written   by	Wolfgang  Helbig
     <helbig@FreeBSD.org>.

BUGS
     The assignment of Julian-Gregorian switching dates to country codes is his-
     torically naive for many countries.

     Not all options are compatible and using them in different orders will give
     varying results.
